Ubuntu 24.04 LXC containers fail to boot after upgrade

So with pve-container 5.1.10 the ubuntu 24.04 template should work then?
But the template was removed from the repo, because we needed first pve-container 5.1.10?
Now we have 5.1.10, but no ubuntu 24.04 template, if i understand it correctly?

Thanks fiona, sorry for the stupid questions, but im confused now a bit either xD

You can get a almost working image from https://fra1lxdmirror01.do.letsbuildthe.cloud/images/ubuntu/noble/amd64/default/ (rootfs.tar.xz), but you have to remove the yml file from /etc/netplan directory.

Hi, please help me! :)
After i updated the ubuntu container 23.10 to 24.04 i have lost networking in GUI but in terminal is ok.
Any thoughts on this? More details here.
Thank you!
 
In the container i have installed xfce desktop and connect to it through xrdp. It is very handy ;)
 
In Proxmox i have dis issues, an upgraded Ubuntu 23.10 to 24.10 container using official Proxmox image is loosing it,s networking in GUI and an official Proxmox image with Ubuntu 24.04_2 has no network after boot but has a valid networking configuration. In the last scenario, only the ping command i was able to make it to work using
Code: 
sudo setcap cap_net_raw+p /bin/ping
. At least in 23.10 upgaded i have the network working in CLI but not in GUI.
Using LXD on a Ubuntu host i have no such problems.
This is what i try to solve using Proxmox forums...
Thanks
 
I have found this in proxmox logs...any thoughts on this...i think this is the culprit:
Code: 
mdProx audit[1156011]: AVC apparmor="DENIED" operation="create" class="net" namespace="root//lxc-102_<-var-lib-lxc>" profile="firefox" pid=1156011 comm=444E53205265736F6C766572202331 family="inet" sock_type="dgram" protocol=0 requested="create" denied="create"

i have managed to get it working...why 23.10 was working and not 24.04 eludes me...
In proxmox edit the container conf
Code: 
nano /etc/pve/lxc/102.conf
file and add
Code: 
lxc.apparmor.profile = unconfined

Success!!!!!!

Hey thanks for this! this finally fixed my issue. What exactly does this do? :p

Figure I will add to this, only my LXC with plex has this issue. I have a homebridge LXC and that updated and ran fine.

I am glad that it helped! I think it disables apparmor for this container.
It is a bug in pve i think which dosen't account for all the changes in apparmour profile for 24.04
 
Hi,

is there a working 24.04 image?

My problem is: I managed somehow to add a Ubuntu 24.04 template to one proxmox server, but I don't remember how. Now I cannot restore backuped containers to my new proxmox server. I tried to copy the template manually (/var/lib/vz/template/cache/), but this does not work. I also cannot create new containers using that template (ubuntu-24.04-standard_24.04-2_amd64.tar.zst).

Also, copying /usr/share/perl5/PVE/LXC/Setup/Ubuntu.pm from the "good" server to the new does not solve the issue.

Thank you

Just use the latest:

ubuntu-24.04-standard_24.04-2_amd64.tar.zst

template from the GUI download. Works for me without any problems ...

Thank you. Now I can restore containers using Ubuntu 24.04, but they won't start. Nevermind, I will reinstall the containers from scratch.
